Crick in the neck what to do?

I just woke up today with a horrendous crick in my neck.  I could hardly move and had five clients booked in at Personal training studios.  I managed to do the session sitting down but it was not easy.  I have has a crick in the neck once before but not as bad as this.  I was unable to look left, right or up.  I was not completely aware of what to do so gave our in house masseuse Krenoula a call and she told me to do the following.

Apply heat to it, so I used deep heat on my neck and back

See a sports masseuse as they can relieve it as it often when muscles lock up in the back although medical professionals are yet to define what it truly is

Give it lots of rest and have relaxing warm baths

The following should help relieve you of a horrible crick in the neck yet they can last a few days.  Keep off the gym when you have a crick in the neck like you would with most injuries and illnesses.  Working through injuries is always the wrong thing to do.
